TDP For Domino incremental backups issue

[balaji419]

We have TDP Domino database backup backing an domino database installed in windows 2008 r2 and we have configured three types of backups for this node like daily,weekly and monthly. Daily will run incremental backup and monthly and weekly will run full database backup and we dont have any archive log backups enabled. This domino server has above 1500 databases. When daily incremental domino backups run it inspects all the databases but only backups 5-10 of the databases(all the database files are similar one getting backed up daily). but whereas When we check from the operating system end we could see lot of databases nsf files modified on that day(All those database files are similar) . Domino database has circular logging set, When we raised pmr support they said, its due to circular logging type all the database is not getting backed up.

They gave two suggestions 1)To disable logging 2)To change logging mode to archive. But till now i didn't get why circular logging doesn't support incremental backups and why alone similar 5 database getting backed up daily(Whether DBIID plays any role here). Any one here faced similar issue or can anyone clear my doubts?

Have you fixed this issue? I am also facing same

If you disable logging, incremental backup will be close to full, since one new e-mail in DB will trigger full DB backup for that database. DBIID change requires backup. If you enable archive mode for Domino transaction logs, you get the full potential of incremental backup since all changes are written in log, backed up to TSM and later on deleted from Domino file system. In circular you reuse file space and you can not save all changes, can not use point in time restore...

Hi Silapen,
Thanks for your feedback. Now what do I have to do to have daily incr domino backup? Please suggest proper config on domino side and TDP side. Thanks

Just enable archive logging mode on Domino side and use domdsmc selective+incr+archlog backup (with log inactivation) on a different schedule (weekly selective, daily incremental, every 12hours archlog backup).

Here is setting from Domino
TRANSLOG_AutoFixup=1
TRANSLOG_UseAll=0
TRANSLOG_Style=1
TRANSLOG_Performance=2
TRANSLOG_Status=1

We have 4 different schedule with domdsmc selective+incr+archlog backup (with log inactivation)

But still incr not picking up all Database, only backed up 3 db, see below log
